Brief Summary:
This is a Phase 2, open-label, randomized, 3-arm study to evaluate progression-free survival (PFS) in patients with recurrent platinum-resistant ovarian, fallopian tube, or primary peritoneal cancer treated with intermittent or continuous regimens of relacorilant in combination with nab-paclitaxel compared with patients treated with nab-paclitaxel alone.

Condition or disease Intervention/treatment Phase
Recurrent Ovarian Cancer Recurrent Fallopian Tube Carcinoma Recurrent Primary Peritoneal Carcinoma Drug: Relacorilant, 100mg QD Drug: Nab-paclitaxel, 80mg/m^2 Drug: Nab-paclitaxel, 100mg/m^2 Drug: Relacorilant, 150mg QD Phase 2

Detailed Description:

Relacorilant is a small molecule antagonist of the glucocorticoid receptor (GR). The goals of this study are to evaluate the efficacy of relacorilant either administered daily (continuous) or on the day prior, the day of, and the day after chemotherapy (intermittent) in combination with nab-paclitaxel in the treatment of platinum-resistant ovarian, fallopian tube, or primary peritoneal cancers compared with nab-paclitaxel alone. The safety, pharmacokinetics (PK), and pharmacodynamic profile of relacorilant in combination with nab-paclitaxel will also be assessed.

Eligible patients will be randomized 1:1:1 to one of the following three treatment arms. Patient randomization will be stratified by treatment-free interval from most recent taxane (relapsed within 6 months vs >6 months) and presence of ascites (yes vs no).

  • Arm A (Continuous relacorilant): Relacorilant starting at 100mg, administered orally, once daily every day in combination with nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle.
  • Arm B (Intermittent relacorilant): Relacorilant 150mg, administered orally, on the day before (excluding Cycle 1, Day -1), the day of, and the day after nab-paclitaxel, in combination with nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle.
  • Arm C (Comparator): Nab-paclitaxel on Days 1, 8, and 15 of each 28-day cycle.

Patients will remain on study treatment until reaching a protocol-defined event of disease progression (PD), experiencing unmanageable toxicity, or until other treatment discontinuation criteria are met. All patients will be followed for progression, subsequent therapies and survival. Patients in Arm C who experience unequivocal PD per RECIST v1.1 will be given the opportunity to receive relacorilant in combination with nab-paclitaxel after discussion with the Medical Monitor.

Adequately treated non-melanoma skin cancers or non-muscle invasive urothelial cancer or other tumors curatively treated with no evidence of disease are permissible.
  • Drugs with a narrow therapeutic ratio that are highly dependent on CYP3A for clearance should be avoided. Caution should be exercised when co-administering known inhibitors of CYP3A with relacorilant. Medicines/food known to strongly inhibit CYP3A should be avoided.
  • Concurrent treatment on other investigational treatment studies for the treatment of ovarian, fallopian tube, or primary peritoneal cancer.
  • Has received a live vaccine within 30 days of planned start of study therapy. Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed.
